A tray rests on an extendible arm consisting of two steel tubes with two different outer diameters. The downward force at the tray center F0 = 1000 N. Determine the downward deflection of the tray center and the tilt angles of the tray about each coordinate axis. The wall thickness of both tubes is 4 mm. Take d1 = 40 mm, d2 = 34 mm, a = 500 mm, b = 300 mm, and Esteel = 200 GPa.
Determine total delay, maximum queue length, and the time that the 20th vehicle to arrive waits from its arrival to its departure.
A horizontal curve is designed for a two-lane road in a mountainous terrain. The following data are known: Deflection angle: 40 degrees Tangent: 436.76 Station of PC: 2695 + 73.89 Side friction factor = 0.12 Superelevation = 8% Superelevation run-off..
A thin-walled cylindrical tank of radius r is subjected simultaneously to internal pressure p and a compressive force P through rigid end plates. Determine the magnitude of force P to produce pure shear in the cylindrical wall.
